Entosphenus minimus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Miller Lake lamprey faces severe threats from habitat degradation and water quality deterioration in its extremely limited range within Miller Lake, Oregon. Dam construction and water diversions have altered natural flow regimes critical for spawning, while sedimentation from surrounding land use activities has degraded spawning substrates. The species' restriction to a single lake system makes it exceptionally vulnerable to any environmental disturbance or catastrophic event.
Habitat
Endemic to Miller Lake in south-central Oregon, this lamprey inhabits the lake's sandy and gravelly substrates where it burrows as an ammocoete larva. Adults require clean, flowing water for spawning in tributary streams connected to the lake system.
